DEMOUNTABLE RIM.

Specification of Letters Patent. Patented Dec. 14, 1920.

Application filed Marclrl, 1918. Serial No. 219,788.

To all t(. ham. 1' 1' may 0011069 '1 1,

Be it known that I, VILLIAM J. P. Moonn, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in De mountable Rims, of which. the following is a. specification, reference being had therein to the accompanying drawings.

My invention relates to certain new and useful improvements in deniountable rims for wheels of various kinds, the object be: ing to enable the rim to be removedfrom the wheel and reapplied thereto with a minimum of labor and effort. \Yith this invention it is only necessary to slightly rotate one single bolt without the removal of any nuts. To this end I simplify the means of holding the removablerim in place, so that said means can be quickly and easily operated whenever a puncture of the the or any other contingency requires that the tire should be removed and a fresh one substituted in place thereof. The invention comprises essentially an eXpa-nsible and contraetihle ring whose free ends are brought together or apart by avery simple mechanism requiring the handling of only a single bolt or its equivalent, the working of which can be performed in a few seconds with but a single tool and with little effort. The invention, therefore, may be said to consist essentially in the construction, arrangement and combination of the various parts, substantially as will he hereinafter described and then more fully pointed out in the ensuing clauses of chums.

In the accompanying drawings illustratin my invention:

l igure 1 is a cross-section of my improved demountable rim.

Fig. 2 is a. longitudinal section of the entire wheel, rim and tire.

Fig. 8 is a detail section in partial plan of the adjoining ends of the expansible ring. together with the mechanism for operating said ends, the latter being in the position which it assumes when the ends have been drawn together and the ring placed in its collapsed position.

rim 1. The fixed rim 1 is enc1rcled by a demountable or removable rim 3, having on one edge of the flange 4, while the opposite edge has the flange 37 which engages the detachable ring .5. This outer removahh of the balls 25 and 27 on the inclined faces of members 19 in the opposite direction from that which they were traveling before; or in other words the ring 14, being a split ring of resilient material will, when the nut 23 is traveling in one direction, be expanded so as to lock the parts together, and when the ring is traveling in the opposite direction the clannping effect will be overcome and the parts released from each other so that the rim 3 can be readily demounted.

\Vheu the ring 14 is tightened by the rotationof the bolt 20 in the proper direction one rounded corner 10 will bear firmly against the flange 10 of the fixed rim 1, while the other rounded gorner 15 will bear firmly against the bead (l of the removable rim 3, which will strongly clamp together the fixed rim 1, expansilole ring 14 and the removable rim 3, so that the latter rim which carries the tire will be locked securely upon the body of the wheel for the continuous circumferel'ice of the wheel. hen it is desired to'rclease the rim so as to take it off the wheel. and put another rim in its place, all that the user needs to do is to rotate the bolt in the proper direction to cause the nut 23 to so travel that it will permit the ends 19 of the split ring to move toward each other and thus release said ring from any clamping action upon the removable rim, or in other words, by unlocking the several parts above mentioned so that the rim 3 can be quickly and easily dem'ounted.

It it to be further noted that the inclined slots 18, through which the arms 24 of the nut 23 pass, lie. at angles to the axis of the bolt 20. Hence, while the arms 24 and their balls or swellings 25 and 27 are acting upon the inclined ends 19 to draw said ends together or apart, the movement of the arms.

24 in the inclined slots 18 will have the further effect of expanding the ends of ring 14 radially and thus binding the'ring 14 more firmly in place, or the reverse effect of causing an inward radial movement of the ends of ring 14 which will assistin releasing the clamping action ofring 14. I wish to say however that these slots 18 may be varied within wide limits. If desired, and they are 7 made of the proper width and size, they may rim 84 is similar to the boxlike or channeled rim -l of the other figures of the drawin'g, except that/it is provided at intervals with inwardly projecting sockets which receive the tenons 36 of the spokes 33. The other parts ofthis modification of the invention are arranged to operate substantially the same way as before, it being noted that there is the same expansible ring 14 which functions the same way in its action with the outer removable rim 8. The sockets 3,)

extend into the interior of the ring 14 and lie betweenv the sides 15 and 16 of said ring, keeping the ring 14 from any lateral displacement while being. expanded or contracted. Many changes may be made in the precise details of my invention without exceeding the scope thereof, and I therefore reserve the liberty of changing the embodiment as may be found necessary.

Referring next to Figs. 9 to 15, I have represented therein another form of the invention which in many respects is the simplest of them all and is designed for universal application and to be operated with perfect ease and efiiciency. In this form the fixed rim 40 is encircled by a demountable or removable rim'41, having the side flanges 42. Said removable rim 41 carries the usual pneumatic tire consistin for example, as in the other figlires of the di'awings, of an outer shoe 12-and an inner tube 1 3,althougl these are indicated merely by way of illustration. The removable rim 41 is shaped on its inner surface with a suitable inclined beveled or curved face, one or more of them, in order that said rim mi ty be slipped easily over the fixed rim 40. In the specimen of the invention shown in the drawings, this removable rim 41 has on its inner surface a pair of beveled sections or faces, as 43 and 44, together with a rib or flange 45 located not far distant from the face 43, said faces 43 and 44 being preferably on lines of different radii so,.that they will be at different distances from the center of the wheel and thus will ointly assist in providing an inclined surface for-the inside of the removable rim, but of course, I do not wish to be confined thereto but reserve the liberty of changing the number of faces and otherwise varying same within wide limits.

The fixed rim 40 is preferably of a boxlike or channel form as in the other figures of the drawings, and has an inner member with a pair of integral parallel sides 46 and 47, one of which 47 is deeper than the other, and the edges of these parallel sides 46 and 47 being preferably inturned or overlapped at 46 and 47 'and further when the wheel is of the disk type, as previously explained,

the pair of annular disks 2 will overlap the inner edges of the sides-4G and 47", as shown 1n l igs. 14 and 15, because in this manner a satisfactoryand efficient welding of the parts is permitted, and the result isa very secure union of the disks 2 with the fixed rim. Of course, the size, shape and precise relation of these various parts may change and be modified in many ways and in different forms. W hen the particular form is adopted which I have described and shown in l igs. 9 to 15, the removable rin], when mounted on the fixed riin, will have its in. cline 4i resting on the edge 0'! the disk 2 which is secured to the inturned edge 4:7. while the inclined face l3 rests upon the part of the disk 2 which is welded to the inturned edge 46, and the inclines 43 and 44 will rise slightly on th se members when the outward and lateral strain, oi the cxpan sihle ringfitl is applied thereto.

The enpansihle ring 50 is However the; most important feature of this nio-iliiied or alternate form of the irn'cntion and this is shown in cross-section in is! and in iside view and partly in section in various figures, say, troni 9 to 15. It is located loosely inside of the hollow interior of the fixed riin 41.0, and concentric therewith and with the surrounding ren'iovalile rini 4:1, and is preferably in'eontaet with one ol the sides; as 46, of said box-like fixed rini 1-0, and also it is in contact with some port-ion of the inner face of the deniountable rini ll, as for example, the inner circumferential head or rib In order to enable the expansible ring 50 to bind and wedge against the re movable rim and press same firmly and clfectively laterally upon the fixed rim, I [ind it desirable to provide one side of said cx-.

pansible ring 50 with an inclined face 51, so that as the. ring 50 is expanded lll'lbi ln' clined face 51 maybe caused to ride on the edge of rib and the eilect will be that the run ll will he moved laterally and the fares 4:3 and 44 caused to mount upon the ad acci'ir vei'lges of the tired riin so that all the parts will effectively interlocli'ee'l.

Fiaid expansihle ring is divided or split at one point so as to leare two coi'itigni'ins bent ends which areseparated more or less from each other and between said ends 52 and the main. portion of the ring 50 are curred integral connections 53. said connections heing thinner and smaller than the main body oi? the ring; and the ends :32 so that they will have more elasticity or ficnihility. tlon.see uientl possible to interpose between the ends 52- a rotataliile member, such as a. cam, wl'iich will force the ends apart and in so doing, will. bend the connections at the same time expanding the ring 50 outwardly and easing it to bind firmly against the rib 45 on the inner surface of the rei'novahle rim, stated above. Une example of expansion device for the separation of the ends is shown in Figs. 9,12, and '13 and consists ot a cam 54 mounted on a bolt 55 which is carried in the side walls 46 and 47, of the fixed rim 40. or rather in the cut-out intnrned parallel sections 56 of said side Walls as shown in ngalnst these ends of the expans' .ile riin.

Figs. 9 and 12- Bolt 55 has a head 64: to which a tool may he applied forturnine; it, and on its other end is a collar 65 secured by a pin or other means. Of course the bolt and cam may be made in one piece if desirmh that is to the bolt may he made with earn projections or arms thereon that will do the Work of the particular cam shown. 1

The cai'n is secured by pin 60 to boll: 55 and has two arms or high parts that are opposite to each other and tha adapted to bear against the ends 52 oi. (wpansible ring 50 during the locking: opei tion and thus expand the ring 50 i that it will clamp tightly against the outer lemountable rini ll. all as clearly shown in l ies. 9, l2, and 1.4-. in Figs. $1 and 12 the position of the cam 5i and its a tns 5% when unlocked is shown in dotted l nes, at which time the cam may be said in a general way to lie parallel with and between the bent ends 52-. or in a direction radial of the wheel; and when the earn locked with the parts 5% ol the cam hearing against said ends 52, the cam is sl'iown in full li in these Fig 9 and with the pro. ,sproportioneo a i shown aslin'ht rotation of the bolt and the f 54, in the present example of. sa. of a turn. to the right or be slllliclel'lt to expand th ing it outwardly ll nu. l'IF to its lorkiing position where it laced in 4.: mus oven is its n ine' again. the cm s shown in tall 1 jarringof the parts tl'i ternal parts of the rim d.-. of the wheel might dis ocat its loclzjingg' position and destroy ins ell'et and thm'chiie in or; this, I. find it desirable to l. lock for holding said earn in silion. Various devices i in he for this purpose. (line Form o have shown in the drawings. a shouldered pin t sorted in parallel rc of cain 54L on on site sides oi. the next a (see Fig. 13 These pins enveloped by springs wl'iich are tensionezl between collars or shoulders 61 on the pins 61 and the opposite ends of the rel s 62, said collars til." fitting within cireu recesses 62 and sliding therein, and there being projecting ends of the pins 61 beyond the collars (31 which are adapted to enter perforations 6G in the wall 46 of the fixed ri n. l0 and the overlapping portions of the wheel disks 2, this engagementof the pin or pins 61 normally taking place under the forcing action of the springs 63. hen the cam 54 occupies its locking position, therefore, the cam is kept in place by means of said pins. and prevented from being disturbed as a result of the motion of the wheel. lVhcn it is desired to unlock the cam, and collapse the expansible ring 50, all that the user needs to do is to first push the pins 61 in- Wardly so as to disengage them from the perforations 66 in the wall 46 and thus set free the cam, after which a wrench or other tool can be applied to the head oi bolt 55, and the latter given a slight movement sufficient to release the cam from the ends 52 of the ring 50. A great variety of tools may be used for the purpose of disengaging the detent or detents 61, and obviously a tool might he contrived which would disen gage said detent or detents and'hold them disengaged while simultaneously rotating bolt 54, but said tool forms no part of the present invention, I do not think it necessary to illustrate or describe the same. inasmuch as a large variety of tools might be used for the purpose.

In order to keep the ring 50 in position while it is being expanded and prevent it from slipping out of place laterally or creeping circumterentially, I find it desirable and important to employ a relatively stationary member which can engage the same at a point opposite to the split or divided point,.and as one example of means of this kind, I employ one-or more dowel pins 57 which are screwed into the fixed rim (see Fig. 11), occupying positions substantially radial of-the wheel, and said dowels 57 having conical or pointed ends 58 which loosely engage correspondin -shaped notches in the expansihle ring 50. By causing these dowels or pins 57 to thus engage the ring the latter is held' in position while the tam device its-operating upon the {lexible ends at the point where the ring is divided. also have the advantage oi keeping the ring 50 in place when collapsed and. prevent it from dropping out of position. It will be further seen that the cam 54 is provided with an encircling flange (37, one side of which is preferably beveled; Said flange has the function of holding the ring 50 in place when it is loose and prevents it from dropping down toward the other side of the fixed rim. The size and shape of the flange 67 may vary, but it will be found to nently and continuously.

These dowels 57, as will be seen,

it is made is bentto a slightly smaller diameter than its collapsed diameter, hence, when it is collapsed. it will he noted that the ends follow back with the cam, keeping in contact therewith more or less closely even when the cam is in its neutral position, as shown in dottcd lilies in Figs. 9 and 12. The fact that the connections 53 are resilient or spring-like so as to give the ends resiliency, and the further fact that the ring formed so that it will react to a position slightly smaller than its collapsed diameter, enables this advantage to accrue in the use of the wheel. 'It may happen that by striking against a curb or other ()llSl'l'llCtlOll, the dcn'iountablc rim will be forced upon the fixed rim with such prcssurc at one or more points as to loosen the ring 50 or cause a certain amount of slack therein, and' this would. result in loosening all the parts were it not for the fact of these spring-like curved ends against which the cam is hearing, but the resiliency of these ends takes up any slack which may, in thismanner, have been occasioned betwecn the ring 50 and the rib 45, and enables the expansible ring to continue its locking ctl'cct perma- This is a great advantage and makes the wheel. more capable of hard usage than is the case withother forms of wheels now in use.

- Having thus described my invention, what i I claim as new and desire to secure by Letters Patent is I.
